Into The Abyss (Merthur/ SuperWhoLock -boyxboy)

Merlin finds himself in a predicament- tell Arthur about his magic and face possible exile, or keep it locked inside with no hope of escape?.

That's just the tip of the iceberg in this tale of love, peril, and magic.

I know this sounds really cheesy, but that's because I'm not good at descriptions. And there is some SuperWhoMer in later(ish) chapters, and there's going to be some Sherlock in there too, so there's that.
